摘要
本文介绍一种用于光盘读写头的二元光学器件。该器件不仅体积小(Φ5mm,厚度1mm),重量轻(小于0.03g),而且同时具备分束、聚焦和跟踪误差信号探测等多种光学功能,衍射效率为26.2%。
Abstract A new binary optical element for optical disk memory read write heads isintroduced,This element is not onlv small in size(5mm in diameter,1mm in thickness),light in weight(<0. 03g),but also with three optical functions,beam splitter,focusing andtracking error signal detection,And its diffractional efficiency is about 26.2%.
